Embodiment Construction
[0044] The present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0045] Such as figure 2 Shown, a kind of SSL / TLS protocol plaintext data collection method based on image flow, described method comprises:
[0046] Step 1) receive the mirrored SSL / TLS packet, extract the records in the packet, generate several complete records, and put them into the record queue; specifically include:
[0047] Step 101) receiving the mirrored SSL / TLS packet;
[0048] Step 102) extract the first record from the data packet, check whether there is a cache record in the record buffer area, if there is no cache record, then directly calculate the length of the first record received; if there is a cache record in the record buffer area, After splicing the data packet into the cache record, calculate the length of the first record in the current cache;
[0049] The SSL / TLS protocol record encapsulation format is shown in Table...
